Application filed July 31, 19,08, Serial No. 446,3,54.

To all whom it may concern:

Be it known that I, QWEN K. HARRY, a citizen of the United States,residing at Dallas, in the county of Dallas and State of Texas, haveinvented certain new and useful Improvements in Land-Rollers; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relatesto land rollers, and the object of the inventionis to provide a roller having a corrugated outer rim which is secured inposition solely by a bonding material inserted while in plasticcondition between such outer rim and the inner rim which may also beformed with a corrugated surface. 7

With this object in view the invention consists of the novelconstruction hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a side elevation of thedevice. Fig. 2 is a transverse section of one of the rollers. Fig. 3 isa detail view showing the manner of connecting the end castings to theinner corrugated rim. Fig. 4 is a. view in elevation showing two rollersmounted on the same shaft. Fig. 5 is a view partly in section of one ofthe rollers constructed in a slightly.

different manner. Fig. 6 is an elevation of the roller shown in Fig. 5.

Referring to the drawings in detail, 1 indicates a framework in whichthe rollers are mounted, 2 the tongue, 3 the main axle, and 4 thesupport for the drivers seat 5. In the construction of the rollersproper, I employ, preferably, an outer corrugated rim 6 and an innercorrugated rim 7, these rims being separated by a suitable fillingmaterial which is inserted in plastic form and which when it has becomehard forms a part of the body portion corresponding to the felly of awheel.

Secured to each end of the roller is a castin 9 formed with the spokes10, and provided with a central aperture 11, constituting a bearing forthe axle 3. The outer ends of the spokes are provided with laterallyprojecting members 12 and 13 which are concaved on their inner surfacesto conform to the surface of one of the corrugations of the rim' 7 andare secured to said rim by means of bolts 14.

It will be observed that the outer corrugated rim 6 of the roller servesto leave the 7 surface of the ground .over which it is passed withgrooves or shallow'furrows, while the inner corrugated rim providesgreater rigidity with the use of a given amount of metal, or a plate ofgiven thickness. The corrugations serve to hold the cement or otherplastic material in position and such plastic material constitutes thesole support of the outer rim 6.

In the modification shown in Fig. 5 the rim is formed in substantiallythe same manner, but the end members by means of which the roller ismounted on the main axle are formed of disk-like members 15havingoutwardly-turned flanges 16, the latter being bolted to the innerrim 7 by means of bolts 14 Secured to members 15 are sleeves 17 whichproject outwardly far enough to prevent the edges of the rollers fromcontacting when two rollers adjoin each other on the same shaft.

What I claim is:

1. In a land roller, an outer rim having a corrugated surface and abonding material connecting the rim with the roller proper.

2. In a land roller, an outer rim having a corrugated surface, an innerrim formed on the roller proper, and a bonding material connecting thesaid rims.

3. In a land roller, a roller proper having a rim of corrugatedmaterial, an outer rim encircling the rim first-mentioned, and a bondingmaterial connecting the rims.

4. In a land roller, a roller proper having a rim of corrugatedmaterial, a second rim having a corrugated surface encircling said rim,and means for connecting said rims.

5. In a land roller, a roller proper having a rim of corrugatedmaterial, members supporting said rim, said members provided with curvedouter ends conforming to the corrugations of the rim, an outer rimhaving a corrugated surface, and means for connecting the two rims.

6. In a land roller, a roller proper having a rim of corrugatedmaterial, members for supporting said rim, devices on the ends of saidmembers provided with curved faces conforming to one of the corrugationsof the rim, an outer rim encircling the rim first-mentioned, and abonding material connecting the two rims.

7. In a land roller, a main frame, an axle journaled therein, a rollermounted on said axle, said roller consisting of supporting membersadapted to contact with the axle, a rim secured to said members, anouter rim encircling the rim first-mentioned and formed with acorrugated surface, and a bonding material located between the two rims.

8. In a land roller, a supporting frame, an axle journaled therein, aroller mounted on the axle, said roller consisting of members adapted tocontact with the axle, said members formed with devices having outer,

I concaved surfaces, a rim connecting said 3 members, provided withcorrugations engagl ing the concaved surfaces, an outer rim ofcorrugated material, and a bonding material 15 supporting the outer rim.

In testimony whereof I aflix my signature in presence of two witnesses.
